Nonlinear aerodynamic characteristics of a 65-deg delta wing in rolling motion - Implications for testing and flight mechanics analysis

Select Means for Determining Unsteady Aerodynamic Response Characteristics from Static Data

“…Jenkins 3 was the first to compare the static slopes of the experimental data and potentialflow prediction to the unsteady-response characteristics. As can be seen in Figure 18, in those regions between adjacent critical states where the slope of the static wind tunnel data was relatively constant and similar to that of the potential flow calculations, the unsteady response time constant was on the order of zero or one.…”
